From Smithers to Moricetown yes it is and believe you have to take out at trout creek. I was more interested if there is any day floats below the falls at Moricetown. Can't seem to find much and google earth looks like it is just cayon below the falls so maybe only accessible via sleds coming up from Skeena.

Lots of jets launch just above the Suskwa Forest Service Road bridge. There's some decent water above and below that, but much of the canyon between Moricetown and the Suskwa FSR is tanky and not worth swinging IMO. Suskwa to Hazelton is a fair haul if you're drifting and much of that is tanky canyon water too.
